如何优雅地处理由于旧解释器版本导致的失败的未来功能(__future__)导入？

try:
    from __future__ import division
except ImportError:
    print("Failed to import __future__ division")

import sys

if sys.version_info >= (3, 0):
    from __future__ import division
else:
    print("Python version is too old to import __future__ division")

pip install future

from builtins import division
